hbuilderX开发5+App出现首页启动不显示，是什么原因啊？

//创建子页面，首个选项卡页面显示，其它均隐藏；
mui.plusReady(function() {
var subpages = ['souye.html', 'videoPage/classicCenter.html','users.html']; // 'spaces.html',
var subpage_style = {
top: '0px',
bottom: '50px'
};
var aniShow = {};
//当前激活选项
var activeTab = subpages[0];
//选项卡点击事件
mui('.mui-bar-tab').on('tap', 'a', function(e) {
var targetTab = this.getAttribute('href');
var acc = localStorage.getItem("acc") || "";
if(targetTab != "souye.html"){
plus.navigator.setStatusBarStyle("light");
}
if(acc==""){
if(targetTab == "users.html" || targetTab == "spaces.html"){
goHTMLA("login.html")
}else{
if (targetTab == activeTab) {
return;
}
//显示目标选项卡
//若为iOS平台或非首次显示，则直接显示
if(mui.os.ios||aniShow[targetTab]){
plus.webview.show(targetTab,"fade-in",100);
}else{
//否则，使用fade-in动画，且保存变量
var temp = {};
temp[targetTab] = "true";
mui.extend(aniShow,temp);
plus.webview.show(targetTab,"fade-in",100);
}
//隐藏当前;
plus.webview.hide(activeTab);
//更改当前活跃的选项卡
activeTab = targetTab;
}
}else{
if (targetTab == activeTab) {
return;
}
//显示目标选项卡
//若为iOS平台或非首次显示，则直接显示
if(mui.os.ios||aniShow[targetTab]){
plus.webview.show(targetTab,"fade-in",100);
}else{
//否则，使用fade-in动画，且保存变量
var temp = {};
temp[targetTab] = "true";
mui.extend(aniShow,temp);
plus.webview.show(targetTab,"fade-in",100);
}
//隐藏当前;
plus.webview.hide(activeTab);
//更改当前活跃的选项卡
activeTab = targetTab;
}
});

//自定义事件，模拟点击“首页选项卡”  
document.addEventListener('gohome', function() {  
    var defaultTab = document.getElementById("defaultTab");  
    //模拟首页点击  
    mui.trigger(defaultTab, 'tap');  
    //切换选项卡高亮  
    var current = document.querySelector(".mui-bar-tab>.mui-tab-item.mui-active");  
    if (defaultTab !== current) {  
        current.classList.remove('mui-active');  
        defaultTab.classList.add('mui-active');  
    }  

});  

var self = plus.webview.currentWebview();  
for (var i = 0; i < 5; i++) {  
    var temp = {};  
    var sub = plus.webview.create(subpages[i], subpages[i], subpage_style);  
    if (i > 0) {  
        sub.hide();  
    }else{  
        temp[subpages[i]] = "true";  
        mui.extend(aniShow,temp);  
    }  
    self.append(sub);  
}  

/*var user = localStorage.getItem("user")||null;  
if(user==null){  
    logins();  
}*/  

});

这个是双webview主体函数，其中真机调试首次启动时, 'souye.html' 不显示
